Abstract

A industrial method for producing fermented vegetables includes cleaning raw vegetables dipping in salt solution, inoculating strain, fermentation under the condition of sealing and temp control, and vacuum packaging, and features short production period, less consumption of bacteria, and high quality, pure taste and long storage period of fermented vegetables.

Description

A kind of technology of commerial scale production of fermented vegetable by combined inoculation

The present invention relates to a kind of technology of industrialization stain system fermented vegetable.

People's pickling sauerkraut generally is to be the raw material dish with Chinese cabbage, makes through lactic fermentation.Traditional method is to work as container with cylinder or pond, relies on the small amount of lactic acid bacterium of Chinese cabbage surface attachment, and under low room temperature condition, the natural propagation fermentation is pickled.The fermentation back is immersed in the stain liquid and preserves under low temperature environment.This method only is fit to resident family stain dish.The subject matter of its existence has: 1. yeast phase is long, by small amount of lactic acid bacterium spontaneous fermentation attached to the dish table, and generally must be more than 30 days; 2. perishable, especially in the higher temperature environment, easilier cause softening rotten because of mold propagates; 3. the content of nitrite height obviously increases content of nitrite because of sauerkraut is rotten; 4. unstable product quality because the kind of the lactic acid bacteria that the dish table adheres to is indefinite, because of the bacterial classification difference of participation main fermentation process, and makes fermentation dish taste produce difference, and therefore, the sauerkraut taste can not be controlled.In order to address these problems, people have done multiple effort, the patent application of a key name for " suitability for industrialized production sauerkraut method " number disclosed as Chinese patent " 901087505 ", be the Chinese cabbage of will handle with the salt solution sterilization after, be cut into silk, salt solution with 0.5～1% and 5%～10% lactic acid bacteria are stirred in, and pickle the 1-degree 2, in the food bag of again dish silk and leachate being packed into, vacuumize, seal, be put in 20 ℃ ± 1 ℃ indoor fermentation 8-12 day, this method packs vacuum seal after adopting and mixing bacterium, under the uniform temperature condition, the method of fermentation has shortened the phase of pickling, and under certain condition, can prevent to rot behind the envelope.But it is high that this method requires to connect the bacterium amount.If the bacterium amount is lacked when mixing bacterium, can not effectively suppress varied bacteria growing, after pack is sealed,, can produce account tympanites bag because of yeast growth, and because of varied bacteria growing, and cause that the sauerkraut quality descends or goes bad.

Task of the present invention is: propose a kind of pickle the phase short, bacteria using amount is few, pure taste is controlled, long shelf-life, be applicable to the plurality of raw materials dish, the technology of the suitability for industrialized production fermented vegetable that can process continuously.

Task of the present invention realizes as follows: selecting vegetables such as melon and fruit, rhizome, potato class such as group leaf vegetables such as Chinese cabbage, broccoli or blue or green tomato, cucumber, lettuce, radish, potato for use is the raw material dish.

1. raw material dish cleaning:

A, group leaf vegetables select half heart to serve, remove Huang Ye, mashed group, old root, clean desilt, cut partly;

6, melon-fruit-like vegetable: choosing does not have mashed skin, whole fruit, cleans;

Rhizome vegetable such as c, radish: cut the part of damaging by worms, stripping and slicing or sheet clean;

Potato such as d, potato class vegetables: peeling, clean, behind section or the silk again rinsing remove the starch of attachment removal.

2. salt soaks: the dish after will clearing up is put into the salt marsh container, and adding concentration is the saline solution of 5%-8%, soaks the dish of packing into, floods 4-8 hour;

3. connect bacterium: the dish behind the salt marsh is put into round, add leavening, add 30 ℃～40 ℃ warm water stain liquid, soaked the dish of packing into, and stain liquid is evenly mixed with leavening.Leavening is in 6 kinds of lactic acid bacterias such as embryo dish lactobacillus, Lactobacillus brevis, Leuconostoc mesenteroides, pediococcus cerevisiae, streptococcus lactis, selects 3 kinds, and is numerous through pure bacterium expansion, is mixed and made into by 1: 1: 1;

4. after connecing bacterium,, move into fermenting cellar, temperature controlled fermentation, 25 ℃-30 ℃ of temperature control scopes with the round sealing; Round is one to be provided with the ring tank, adopts water-stop, is provided with postive stop baffle, and available location presses thick stick to prevent the pickles come-up, and device movably, shown in Fig. 2,3;

5. pack: will steep good dish, chopping is packed with the strong composite membrane food plastic bag of gas barrier property, vacuum deaeration.

The present invention is owing to the fermentation that can be used for helping vegetables such as leaf class, melon and fruit class, tubers, potato class, and is widely applicable, adopts method of the present invention can steep the multiple fermented vegetable of system.

Because pickled phase of method of the present invention is short, bacteria using amount few (be dish amount 0.5%～1%), sweat seals oxygen barrier, temperature control, no putrefactive phenomenon, the manufactured goods pure taste, content of nitrite is low by (0～0.5mg/kg).

The present invention adopts the combination bacterial classification to connect bacterium, but by various combination selected control fermentation dish taste, pure taste.

The pickled stoste of the present invention adopts the strong PEI composite membrane polybag vacuum deaeration packing of gas barrier property, and without chemical preservative, the shelf-life was not less than 3 months at ambient temperature, and under 15 ℃ of conditions, the shelf-life was not less than 6 months.

The pickled fermented vegetable variety of the present invention is many, and bacteria using amount is few, and quality is good, long shelf-life.

Fig. 5 prevents dish levitating device schematic diagram for the spacing pressure thick stick of installation for fermenting baffle plate;

Fig. 6 is the A-A cutaway view of Fig. 5.

A most preferred embodiment of the present invention, flow process as Fig. 1, Chinese cabbage or broccoli are cut half (whole cucumber, blue or green tomato, the radish section, the starch that adheres to is cleaned in the potato chopping), the salt marsh groove salt of packing into soaked 4-8 hour, after soaking, puts into salt fermentation tank as shown in Figure 2, adding is 1: 1: 1 lactobacillus acidophilus by ratio, Leuconostoc mesenteroides, the leavening that the lactobacillus plantarum combination is made connects bacterium, add 30 ℃～40 ℃ warm water stain liquid, seal, drop into the fermenting cellar of Controllable Temperature, under 25 ℃ of-30 ℃ of conditions, fermentation 6-8 day, pack with the PET/PE composite membrane polybag vacuum deaeration that gas barrier property is strong, promptly become product.

The equipment of realizing said method is the container of cylinder or cuboid, above that along being provided with ring tank 2, loam cake 3 can place ring tank 2, its effect is to realize the sealing oxygen barrier, and the ring tank can be arranged at the inboard (as shown in Figure 3) of container upper edge, also can place the outside of container, as shown in Figure 4, madial wall at container is fixed with several positive stops 5, and its effect is with pressure dish deckle board 6, presses thick stick 7 to be pressed in it down, prevents dish 8 come-ups.
